Probably a ton of other things, but basically, the site is all set, SEO-wise.

Here's what's confounding:

When I do a link:www.example.com in Bing/Yahoo, it shows many backlinks. When I do a link:www.example.com in google, it shows up 0 links. Or when I use a site-ranker like Web Site Rank Tool it's showing 0 backlinks from Google. Any suggestions would be appreciated!

Please read about google new update on penguin and Google envelope ,links are not so popular now as they come across spammy , as for daily updates in Smo don't do daily as google also thinks this as spam spread it out over time maybe twice a month ,and also for hard targeting keywords o rank page one google you have to wait from 3 months to one year like I had to for many sites of my own and clients sites I have been doing seo for over six years I have lots of websites I use in testing as I see for myself what's working or not , I to have sites that were page one then disappear then appear doing the google shuffle they eventually come back it's just google finding new sites and yours will go back

Thanks for taking the time to respond, @Kane. My site went from a PR 1, and just recently a PR 3, so Google must have updated their PR'ings. But I'm just wondering about why link:mydomain.com isn't showing any backlinks in google. Thanks for the Panda and Penguin updates ... although just about every page is rich, quality content complete with quality youtube engineering demonstrations. But the basic message is that Google wants you to do things, just not too many things ... hehe .... Thanks again for your time, Kane.

Most or all of those social media sites add rel="nofollow" to all external links. And the value of links from most directories is dubious at best (not that I don't ever use them but they are suspect).

Any link that can be obtained in an automated fashion probably isn't worth having and if you are that religious about social media posts (i.e. YouTube everyday‽) you might, in the eyes of a search engine seem like a 'robot.'

I don't think Yarden is right . Google not always list all the back links. I had 263 back links in webmaster tools , but one fine day its showing only 63. I have more unique back links displayed in Alexa.Then i tried "SERPAttacks" ,it too show erroneous data. I am too confused . Don't know where to look for reliable list of back links.

Hi Susan. Thanks for responding. I understand black hat and white hat SEO techniques, but still, many of 'em are unreliable at best. There's a difference between rel=nofollow and rel=noindex pages. Twitter is rel=nofollow, yet I get indexed there all the time. As far as guestimating the number of backlinks you have out there, it's like you really just have to keep doing what you're doing. Keep backlinking; some tools are more accurate than others.
